`squareABCD` is a parallelogram. A circle passing throught D, A, B cuts BC in P. Prove that DC=DP.

ABCD is a parallelogram . The circle passing through the vertices. A, B and C intersects CD (or CD produced) at E. Prove that AE=AD .

ABCD is a parallelogram . The circle passing through the vertices. A, B and C intersects CD (or CD produced) at E. Prove that AE=AD .

ABCD is a parallelogram. Any line through A cuts DC at a point P and BC produced at Q.Then,
